Sahih Muslim , Book 10, Hadith 3830 (USC-MSA) ⓘ
It is narrated on the authority of Humaid that Anas b. Malik was asked about the earnings of the cupper. He said: Allah's Messenger got himself cupped. His cupper was Abu Taiba and he (the Holy Prophet) commanded to give him two sa's of corn. He (the Holy Prophet) talked with the members of his family and they lightened the burden of Kharaj (tax) from him (i. e. they made remis- sion in the charges of their own accord). He (Allah's Apostle) said: The best (treat- ment) which you take is cupping, or it is the best of your treatments.
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، وَعَلِيُّ بْنُ حُجْرٍ، قَالُوا حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنُونَ ابْنَ جَعْفَرٍ - عَنْ حُمَيْدٍ، قَالَ سُئِلَ أَنَسُ بْنُ مَالِكٍ عَنْ كَسْبِ الْحَجَّامِ، فَقَالَ احْتَجَمَ رَسُولُ اللَّهِ صلى الله عليه وسلم حَجَمَهُ أَبُو طَيْبَةَ فَأَمَرَ لَهُ بِصَاعَيْنِ مِنْ طَعَامٍ وَكَلَّمَ أَهْلَهُ فَوَضَعُوا عَنْهُ مِنْ خَرَاجِهِ وَقَالَ " إِنَّ أَفْضَلَ مَا تَدَاوَيْتُمْ بِهِ الْحِجَامَةُ أَوْ هُوَ مِنْ أَمْثَلِ دَوَائِكُمْ " .
